DOMESTIC COOKING VESSEL.

Specification of Letters Patent.

Patented Jun@ 2, 190s.

Application filed Sisptember 27, 1906. Serial No. 336,488.

T o all whom it may concern:

Be it known that I, ALoNzoW. CRAM, of Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in Domestic Cooking Vessels, of which the following description, in connection with .the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to certain improvements in domestic cooking vessels such as are ordinarily provided more especially to such vessels as tea-kettles and coffee pots which must be filled somewhat frequently, and which are ada ted to permit the liquid to be poured there rom.

The invention further relates to certain improvements in that class of covers for vessels of the above character, whichare adapted to be opened automatically by the weight of the liquid poured thereon to permit it to 'liow into the vessel, and to close automatically thereafter.

The principal objects of my invention are to reduce the cost of manufacture of these articles and at the same time to render them more hygienic by constructing .them so thatthey may be more easily and thoroughlyl cleaned.

Another object of my invention is to produce a form of automatic cover which may be manufactured at less expense than certain forms which I have previously produced, which are also less likely to get out of order and which may be ap lied directly to the vessel without the emp oyment of an intermediate insertible cup, as has been necessary with my said prior; devices.

A further object of my invention is to provide an automatic cover of the above described character which may also perform the function of a strainer for the liquid as it is poured from the rece tacle.

I accomplish these objects by the means shown in the accompanying drawings, in which,

Figure 1 is a plan view of a tea kettle comprising my invention. Fig. 2 is a central sectional view thereof on the line 2-2, Fig. 1. Figs. 3 and 4 are enlarged detail sectional views, also taken on the line 2-2 of Fig. 1,

showing the parts in different positions. Fig. 5 is a plan view, partly broken away, of the parts in the position of Fig. 3. Fig. 6 is a sectional view on the line 6-6, of Fig. 7, of

the coffee pot provided with a modified form with covers, and

of m invention. Fig. 7 is a lan view of the evice shown in Fig. 6. lgs. 8 and 9 are respectively sectional and plan views illustrating a modified form of my invention. Figs. v10 and 11 are respectively, side elevation and plan views illustrating another modification.

The tea kettle body shown in Figs. 1 and 2, consists of a lower portion a and a top portion tightly soldered thereto, as indicated at b. The top portion comprises an inclined side portion b and a horizontal top portion b2, and an opening b3, of approximately the size of the ordinary kettle opening, is formed in said inclined side portion b. A s out c is inserted in said opening b3 and sol ered in place, said spout being grooved and pro- ]ected at the middle of its front side to form a pouring lip c. Said opening is ada ted to be closed by means of anautomatica ly tipping cover or lid d, and to provide means for ivoting said lid I provide an inwardly projecting ear c3l at each side of said opening, each having a slotor notch c2 therein, disrsiosed at opposite, corresponding points.

houlders or lugs d2 are provided at opposite sides of said cover, at points corresponding to the position of the notches c2, the width of said cover from said shoulders to its front end being slightly less than the distance between the bottoms of said notches, and the thickness at the edges thereof between the same points being less than the width of said notches, so that it may be readily inserted in said opening with its edges in said notches, to bring its shoulders d2 into engagement with the up `er side of said ears c3, or the inner side of e spout c. The cover will thus be dpivotally supi'prted on said shoulders d2 an may swing t ereon into the position to close the openingb3, the slots c2 being of sufficient width, and the ear ortion in front thereof being raised above t e portion in the rear thereof to a sufficient extent to permit said movement. In moving the cover to its closed position, the edge thereof in front of the pivotal shoulders d2 swing into close proximity to the inner side of the spout, and the edge portion in the rear of said shoulders seat against the inner side of the s out, so that the opening b3 is closed as tight y as is necessary. The cover is counterbalanced by means of the weight e, secured to the under side thereof, in the rear of the shoulders d, so that the cover will be normally held in its closed position. The area of the portion of the cover in front of its pivotal sup ort is weight of water in front of its pivotal supports is much greater than that in the rear thereof, and, as the'y weight e isbut little more than suiiicient to hold the cover in its normal position, the weight will be at once loverbalanced, and the ,cover will tip and permit the water to flow readily into the vessel, as shown in Fig. 3, the cover'automatically returning to its normal position when the iow has ceased.

A valve plate f is ivoted to the lower portion of the cover d) by means of a lug f', which passestherethrough, and is suitably bent to hold it in place, said plate f being concaved to correspond to the upper side of the cover, so that it may he closely thereon and close a series of strainer apertures d3 formed in cover d beneath the same. The kettle having'v been filled by pouring the'water into the enlarged spout c, as above described, it may be emptied by pouring the water out of the s out in the ordinary manner, the water owing through the strainer apertures d3 and lifting the plate f, as shown 1n Fig. 4, the water pressure upon the inner side and lower portion of the coverl acting to hold the same in its closed position. The water will thus be strained as it is poured out, and as the cover can be easily withdrawn from the opening, access can be readily had to the interior of the kettle to clean the same, while the strainer in the cover d may also be easily cleaned. A kettle thus constructed may be made at materially less expense than those having the usual cover and spout, and,

' in addition to the advantages from the hyi top of the gienic point of view, I am enabled to employI a rigid unjointed bail handle g which is constantly held upright, so that it will not become too hot to be held in the hand. If, however, it is desired to a ply my invention to a ketttle having the or nary discharge spout leading from a lpoint near thel bottom, the top opening wil be provided in the middle in the ordinary manner. In this case, however, if an insertible cup, such as shown in my prior patent ##800080, of Se tember 19, 1905, is not employed, and the ettle is constructed with special reference to my invention, I rovide a concave recess in the kettle body as shown in Fig. 8, in the middle portion of which the opening :1;2 is formed. Oppositely disposed notches, as indicated at ma in Fig. 9, are formed in the edge portion surrounding the opening rc2, and a cover y, having lu s or shoulders y thereon, is provided, all sulgistantiall as previously described with relation to t e construction of Figs. l to 4. In this instance, however, the fportion in front of the pivot shoulders is o sulicient area to enga e the under side of the body portion .,whi e. the portion in the rear thereof engages the upper side of said body portion when the cover is in its closed osition.

In Figs. Gand 7I show another form of my invention, as applied 5to a coifee or tea pot m, \which is open at its upper end and is rovided with a curing groove or lipm. he cover or lid n 1s similar to the cover d already described, it being rovided with strainer holes n adjacent sai lip m', which are covered by a valve plate o. In this form of my invention, however, I preferabl provide la pair of pivot lugs p in each side o 4the body m and at opposite points, 'and' I provide the lid fn, with an upwardly rojecting flange n2, at each side thereof, eac having therein an inclined slot n3, which leads from the front end thereof and is adapted to receive the corresponding pivot pin p. Said flanges are extended about the rear portion of the lid and are practically continuous, the rear portion n4 thereof being turned outwardly so that it engages or seats against the side of the vessel at its upper end. The portion of the lid in the rear of the slots n3, or the rear portion thereof is counterwei hted, as indicated at g, so as to hold said ange ortion n4 inengagement with said side, su stantially as in the forms of my invention reviously described. The front ortion ofp the lid n is of greater area than t e rear portion, and is adapted to fit the corresponding portion of the vessel when in its normal position. In inserting the lid fn, into the vessel, the front portion thereof ispassed into the body in the rear of the ivot lugs so that the latter may enter the s ots 'n3 an ivotally support said lid. Obviously the s ot may be formed in the wall of the receptacle and the pivot lug on the lid, as shown in Figs. 10 and l1, in which m0 indicates the side wall having an o en, forwardly extending, inclined slot m2 t erein and n0 the lid which is provided with a pivot lug fm,4 adapted to be passed into said slot, so as to be pivotall supported therein. This construction would7 be necessary when the receptacle was of earthenware, so that it would not be possible to solder the pivot lugs thereon. The pivot receiving slots are inclined upwardly from front to rear in each instance, so that they are moved towards the vertical as the receptacle is tipped to pour over its lip. If the slots were Oppositely inclined or even vertical the cover might sli out of place when the receptacle was tippe lA combined automatically opening and closing cover and strainer is thusprovided,

Patent is 1. A receptacle having a top opening provided With a pouring lip in combination with a pivoted cover balanced normally to close said opening, engaging the receptacle to y limit its closing movement, adapted to open automatically to permit the liquid to flow therein, and having a series of strainer openings formed therethrough, and a valve plate for closing said strainer openings connected to said cover, substantially as described.

2. A receptacle having a top opening provided With a pouring lip at one side, and means for normally closing said opening comprising a main valve adapted to open automatically to permit flow in one direction,

and a supplemental valve adapted to open automatically to permit low in the opposite direction, substantially asdescribed.

3. A receptacleI having a top opening provided with a pouring lip at one side, a pivoted covernormally closing said opening and movable to permit flow into said receptacle,

said cover having an opening therethrough,

and having a valve for normally closing said o enng and movable to permit flow theret rou h from the reeeptac e, substantially as descri ed. l

4. A receptacle having a top opening, a removable cover for closing said opening pivotally supported at each side thereof and inter-v mediate its ends, one member of each ivoted support being provided With a pivot ug and the other with an open slot adapted to receive said lug, substantially as described.

5. A receptacle having a pouring lip at one side thereof and a top opemng, and a removable cover for closing said opening, 'pivotally supported at each side thereof and intermediate its ends, one member of each pivotal support being provided with a pivot lug and the other with an open slot, inclined up- Wardly from said pouring lip and adapted to,

receive said pivot lug, substantially as described.

In testimony whereof, I have signed my name to this speciication, in the presence of two subscribing Witnesses.
